Foam systems have been attracting extensive attention due to their importance in a variety of applications, e.g., in the cleaning industry, and in bubble flotation. In the context of flotation chemistry, flotation performance is strongly affected by bubble coalescence, which in turn relies significantly on the surface forces upon the liquid film between bubbles. Conventionally, unusual short-ra...

Among the methods of preliminary opening refractory gold before sorption cyanidation, technology bacterial oxidation is widely used today. Although this has many advantages, specialists most enterprises around world using are faced with problem foaming in bio-oxidation reactors. This article discusses possibility oxidative roasting processing foam product process flotation concentrate a separat...

Inorganic electrolytes are assumed to significantly impact the flotation performance of graphite resources; however, underlying mechanism is still unclear. In this work, effect three inorganic salts, including KCl, MgCl2, and AlCl3, was studied on graphite. Flotation results indicated increased recovery with addition KCl regardless pulp pH. MgCl2 improved under acidic slightly alkaline conditio...

Accurate and rapid identification of mineral foam flotation states can increase utilization reduce the consumption reagents. The traditional process concentrates on extracting features from a single-modality image, accuracy is undesirable once problems such as insufficient image clarity or poor boundaries are encountered. In this work, classification method based multi-modality fusion CNN-PCA-S...

A new sensitive chromogenic reagent, 9,10-phenanthaquinone monoethylthiosemicarbazone (PET), has been synthesized and used in the spectrophotometric determination of Tl(III). In HNO3, H2SO4 or H3PO4 acids, PET can react immediately at room temperature with Tl(III) to form a red 2:1 complex with a maximum absorption at 516 nm. The different analytical parameters affecting the extraction and dete...

Methylene blue was efficiently removed from aqueous solution by foam flotation using a rhamnolipid a biosurfactant as a dye collector. The effects of four parameters, namely, pH (1.5–11.5), frother concentration (5–65 ppm), aeration rate (2–6 L/min) and rhamnolipid to methylene blue weight ratio (0.5–6.5), on dye removal were studied and optimized using response surface methodology. Results...
